Dental question about observed-topic:gum-and-tooth-sensitivity

Sensitivity can come from exposed dentine, enamel wear, gum recession, decay, a crack, or pulp inflammation, so treatment depends on the finding.

Dentine contains microscopic tubules that can transmit temperature or touch toward the pulp when enamel is worn or the root surface is exposed. A short sharp response differs from pain that lingers, starts without a trigger, or is linked to chewing.

Use a soft brush and gentle pressure, clean between the teeth, and consider a desensitising toothpaste used consistently as directed. Avoid repeatedly testing the painful tooth and arrange an examination to identify decay, a defective restoration, wear, recession, or a pulp problem.

See a dentist when sensitivity persists, increases, affects one tooth, or follows a filling, whitening treatment, crack, or dental injury. Swelling, fever, or severe spontaneous pain needs prompt care.

Ask where the sensitivity originates, whether the pulp is healthy, and whether fluoride treatment, bonding, a filling, bite adjustment, or root canal treatment is indicated.
